. To all iuiio m, it may concern:

Be it known that I, ABRAM CnlVIOTT, Jr., a citizen of the United'States,-residing in Philadelphia, Pennsylvania,have invented certain Improvements imPilot-Btirners for Gas-Stoves, of which: thezfollb'wing: is a specification. 1 -n My inventi on relates .',to certainimprove-- nientsmiprlot burnersfor gasstov'eswfl l The main object of the invention' is to construct aismall pilotburnerinfiwhich the gas can be ignited on the outside ottlie stove and fianiewill be carriedzinto the stove and properlyignite the gas escaping frointhe burners of the stove." i p p A further object of the' invention' is to make the; burner .in one piece, as fullyQdescribed hereafter. Ir'iithe accompanyingidrawings "Figure 1, isia perspective view (if: myiniproved pilot burner; Fig. 2, is a side view of the burner;

Fig; 3, is a plan 'view of thefburner; Fig. 4, 1s a=longitudinal sectional view on the line 4l'4.-, Fig. 3; Fig. .5, is a transverse sectional view on the line 55 Fig. l; 6, is a diagram view illustratingmy invention as applied to a gas stove, and Figs. 7 and 8, are views illustrating modifications ot' the invention.

A is the pilot burner having av body portion B and arms G, ,C, in the present instance cast in one piece. Onthe body portion are ears '1), b by which the pilot burner is secured to the casing D of the stove. The

pilot may be placed as indicatedin Fig, 6,

' so as to direct and carry' the flame to the two burners d, d. The body portion Bhas a narrow longitudinal slot 17 throughout its length connecting with a transverse slot formed in the arms C. 'In the'bodyv of the burner. is a longitudinal partition 6 extending to a point. about midway of the body portion and forming two chambers f,if."

F is the gas-supply'pipe providedwitha suitable valve,ar 1d g is the air intake openwing located as sliown, so that a' certain i Specification of Letters Batent.

upper edge of the body and tliroughthe arms C and ou-t'the openings it inthe ends of the arms, a cei'taimportion ofythe gas escaping through the slots b'fand'c} thus. there is a narrow fla'me of gas escaping throughout the entire length of the arms C,",C,ai1d

fromthe endsof the arms sothat guanine gas is ignited at the {point a; F i.g.-4;;*oirt1ie outside of the gas r-a'nge or heate1",the flame travels along the upper edgeofthebody portion and along the arms," igniting the gas which escapes from the endsof theburn ers andthe flame-projected will ignite th e gasescaping fromt'he burners d,

It wil benot-Tced in Figf iythat the great est'diameter oiE the gas clianiberislat the p oint'where the flow of egas' is dit erte'd; the chamber being tapered toward each "end from this point: 'IhQportioii ff of the chamber is narrowatthe reanendaiid it is also narrow at the point where the body portion joins the arms. 'By this construction an even flow of gas is produced.

I prefer to make the burner in one piece, asshown in Fig. 1, but it will be understood that it may be made, in some instances, in

two pieces, bolted together, as shown in Fig.

7, without departing'from the main feature ofthe invention. In some instances, I may make the pilot burner with single arm, as in Fig. 8, 1n place of the two arms shown.

-I claim 1-. A pilot burner for stoves comprising a slotted, hollow body portion adapted to .ex-"

tend from the outside to the inside of the stove, the said slot in'thebody portion also leading from the outside tothe inside of the stove; a slotted hollow arm projecting from the inner endof the-bodyp'ortion, said body portionhaving a longitudinal partition eX- tending part-way of its length; an air inlet and a gas inlet communicating -w ith the chamber, below the partition whereby the.

body portion of the burner beyond the end of the partition, an air inlet, and a gas inlet communicating with the chamber; below the 'lengththereof.

its upper edge and two arms connected to the body portion and each having a slot in the" upper edge, the slot in the arms com- 'municating with the slot in the ,body

or tion,' a longitudinal partition extending from the rear of the burner,' an abutment adjacent the end of thepartition, the chamher in the body portion tapering toward each end from a .theabutment, an means for supplying gas int about on a line with to the burner.

. 6. A burner comprising a hollow bodyportion having a slot formed therein, the'inner surface of the hollow body portion tapering gas inlet and the slot; and a member having I a deflecting surface and positioned within the hollow body portionQto distribute the gas throughout the length: of the slot,

5. A burner comprlsing a hollow body portion having a slot and a gas inlet formed therein; a partition extending between the gas inlet and the slot; and a member having a deflectingsurface and located adjacent the end of the said partition for distribut .iiiguthe gas-throughout the length of the 3 t 6. A burner .oonsiprising'" a hollow body portion having a 0t formed :therein, the

inner surface of the] hollow body portion tapering in opposite directions andhaving a gas inlet formed therein; a partition extending between the gasinlet and the slot and terminating adjacentthe widest portion of the hollow body; and means adjacent the end of the partition for distributing the gas along the said slot.

7. A burner comprising a hollow body portion having a slot formed therein, the inner surface of the :hollow body portion tapering'in opposite-directions and having a gas inlet formed therein; a partition extending between the'g'as inlet and the slot and terminating adjacent the Widest portion of theliollow body; and a member having a deflecting surface and located adjacent to the end ofthe' partition for distributing the' gas alon the said slot. a 1

8. A urner comprising a hollow body portion having a gas inlet and an outlet ormed therein; a partition extending between the gas inlet and the outlet-{and a member'h'aving a deflecting surface andlocatedadjacent the end of the said partition for deflecting the gas toward the outlet.

In testimony whereof, I have signed my name to this specification, in the presence of v two subscribing witnesses.
